Can confirm. Did a ROT-13/15 (vowels vs consonants, if it matters) test on _smart_ collegues. Turns out they fear the worst and start top-down.

  Were they experienced at breaking ciphers? Plenty of smart people don't jump straight to a solution when seeing a ROT13 ciphertext, whereas I think most people who are experienced would realize pretty quickly there seems to be a simple transformation going on.

  One of the first things I was taught in math class at university. If there are two potential solutions, one extremely unlikely but quick to verify, and one more likely but hard to verify, start by the very unlikely one!

    What if there are hundreds of those?

      Script it!

  Are you saying you did ROT-13 on vowels and ROT-15 on consonants? If so, that isn't a conformal mapping so how do you reverse it?
  • jcims 6y ago
    It is if you operate on two distinct sets, eg vowel in/vowel out.

    Well, if you can't reverse it, then wouldn't that make it really secure? :)
